Application filed May 27, 1818.

To all whom it may concern Be it known that I, NORMAN A. FULLER, a citizen of the United States, residing at Yamhill, in the county of Yamhill and State of Oregon, have invented certain useful Improvements in Loaders, of which the "following is a specification, reference being had therein to the accompanying drawing.

T he present invention has reference gen orally to improvements in that class of inventions known as loading and unloading, and more particularly relates to loaders espec'ally, though not necessarily, adapted for loading manure. I

The primary aim and object of this invention contemplates the provision oi"- novel cooperative conveyors, one or which is adjustable relative to the other and operably connected thereto so that they may cooperate with each other in elevating the material being loaded.

lt is an equally important object of this invention to provide novel supporting means on the truck body which is turnable with respect to the truck body so that the conveyors may be positioned transversely on the truck body and 'eadily and effectively extended to assume an operative position.

is an additional object, the invention con lates the provision of novel loading operably connected to th elevating means for loading the material on the elevatin conveyors.

More particularly, this invention embraces the provision of novel means for raisi ar'l owering the movable conveyor on orting means so that the movable conveyor may be adjusted in various positions with respect to the ground.

is a further improvement, the invention .bly arranged between the two elevating conveyors, the mounting of such means being constructed so as to also slidably c0n nect the two conveyors with respect to each other. 7

Similar characters of reference are emeyed in all of the above described views to indicate corresponding parts.

Referring now, more particularly, to the accompanying drawings there is provided a supporting truck or vehicle consisting of a main stationary platform 1 from which depend bolsters 2 made rigid with respect to the platform by braces 3. A rear axle 4 is carried by the rear bolster while the front axle is connected to the front bolster for turning movement. Ground wheels 6 are journaled on the respective ends of the axles while a tongue 7 extends from the front axle. A secondary turning platform is now provided and consists of a plate-like body 8 on the respective side edges of which are 2 carried guides 9 disposed to lie above the sides of the main platform 1 when the loader is in a position for transportation as indicated in Fig. 1. Suitable fastening means 10 extend through the body 8 and platform 1 for turnably connecting the secondary platform and the main platform while annular bearing bands 11 are carried by the adjacent bases of the two platforms to facilitate the turning movement of the secondary platform with respect to the main platform. T he inner faces of the guides 9 are provided with opposed longitudinal grooves 12 in which are slidably mounted longitudinally extending ribs 13 carried by the outer side faces of rack bars 14, for a purpose as will presently appear.

With a view toward providing the improved stationary conveying means relatively high uprights 15 are mounted at the ront ends of the guides 9 while short stand ards 16 are mounted adjacent the opposite side edges of the plate-like body 8. Side plates 17 are rigidly connected adjacent the upper ends of the uprights 15 and the standards 16 and are arranged. in opposed relation with respect to ca; h other and inclined toward the center of the guides. A shaft 18 is journaled transversely to the upper ends of the side plates 17 and carries a roller 19. A transverse shaft 20 is journaled adjacent the lower end of the plate 17 and also carries a roller similar to roller 19. A conveying apron 22 operates about the rollers and carries transverse slats 23.

Suitable means have been provided for transmitting rotary motion to the stationary conveying means. In accomplishing this purpose a longitudinal shaft 2i has its respective ends journaled in bearings 25 carried between the standards and the uprights. A pulley wheel 26 is carried by the shaft while belt operates thereabout and is connected to a suitable source of power for transmitting s able rotary motion to the shaft 24. A lnveled 28 is carried adjacent the front end of the shaft 24-. and meshes with a relatively large beveled gear 29 carried by a transverse shaft 30, the respective ends of'which are journaled adja'ent the lower ends of the uprights 15. A. sprocket wheel 31 is also carried by the shaft while a chain 32 operates thereabout and is also trained about another sprocket wheel 33 carried by the upper shaft 18. By this arrangement it will be appreciated that when the shaft 2%: is rotated owing to the gears 23 and 29 which are in mesh with each other, the shaft will be retated and by reason of the sprocket wheels 31 and and the chain rotary motion will be imparted to the shaft 18 so as to actuate the conveying apron 22 causing the upper lay to move upwardly.

As intimated, an improved movable confork which meshes veyer has been provided for cooperating with the stationary conveyer in elevating the material to be loaded. In reducing this feature of the invention into practice, two relatively long opposed side plates 3% are employed. A shaft 35 is journaled through the upper ends of these side plates while a roller 36 is carried thereby. ver this roller operates a slatted conveying apron 37 which is also trained about another roller 38 carried by a transverse shaft 39 journaled in the lower ends of the plates 34.

For the purpose of operatively and slide.- bly connecting the movable conveyor to the stationary conveyer shafts 40 are journaled one end within suitable bearings e1 on the outer face of the upright 16 and the other end in suitable bearings at the top of the stationary conveyer. As will be appreciated upon reference to the drawings this shaft is inclined and a beveled gear 42 is carried by the upper end thereof and meshes with another beveled gear 43 on the shaft 18 so as to rotate the shaft 40 therewith. A bar id is mounted on the opposed upright and standard and is arranged in opposed relation to the shaft 40 for the purpose that will presently appear. Arms 45 and 1 5 are now provided. The arm l5 terminates in a box 46, which is arrangerL about the shaft 1-0 so as to be slidable thereon. A beveled gear l? is slidably and non-rotatably connected to the shaft 4-0 and is positioned within the be: so to be slidable therewith. A fork 48 is formed on the upp r end of the arm and is provided with journaled openings for rotatably receiving one end of the shaft 35 while journaled through the be); and the fork 48 is another shaft 49, a beveled gear 50 is carried by the lower end thereof and is positioned in the box so as to mesh with the sliding beveled gear 4'? whereby when the shaft 10 is rotated through the shaft 18, rotary motion will be consequently imparted to the shaft 49 and by reason of another beveled gear 51 on the upper end of this shaft and within the with a beveled gear 52 carried by the shaft 35 this last mentioned shaft will also be rotated simultaneously with the shaft 18. The bar 46 terminates at one end in a bearing 53 which is slidalnv engaged on the inclined 4% while the upper end of the arm l6 terminates in another bearing 54 in which is journaled tr e other end of the shaft 35.

Cooperating with the means for operably and slidably connecting the conveyers to geth r is a means for slidably connecting the movable conveyor to the turnable f; me. .l'n reducing this feature of the invention to practice short uprights are formed on tile outer ends of the raclrbars l Vindlasses are operably connected these uprig ts while cables 57 have their respective ends connected to the windlasses and to the lower ends of the respective side bars as.

l awl and ratchet mechanisms 57 are operatively mounted on the uprights and the windlasses 56 for maintaining the lower ends of the removable conveyer in various positions of adjustment. By means of the windlasses, the lower end of the movable conveyer of course may he raised and lowered with respect to the ground when the machine is in the position as indicated in Fig. 2. In sliding one conveyer relative to the other a shaft 58 is journaled through the short standards 16 while cog wheels 59 are carried to the respective ends of the shaft 58 and arranged so that the teeth thereof mesh with the teeth of the rack bars 14. A crank handle 60 serves as a means for rotating the shaft so as to consequently slide the rack bars and move the movable conveyer.

As hereinhefore stated. an improved loading means has been provided. In reducing this feature of the invention to practice, longitudinal beams 61 are extended from the side plates 34- to a point substantially intermediate the ends thereof being incid ly arranged longitudinally thereof and pro ecting beyond the lower end of the movable conveyer. Standards 62 have their lower ends connected to the outer faces of the side plates $3 adjacent the lower ends thereof, and have connected thereto at points approximately intermediate their ends the beams 61 so as to miintain the latter in a horizontal plane. Braces 63 serve insure the rie" l relation between the standards and the pla es 3a. A cross bar (ll is arranged y between the upper ends of the standards and is provided on its upper L with plurality of vertical slots 65 p i are that ill-presently appear. A cross beam 66 is arranged transversely between the longitudinal beams 61 adjacent the inner ends thereof while a plurality of supporting rods 6'? have their inner ends pivotally connected to the beam 66 and rest in the slots 6-5 in the cross bar and project beyond. Loader arms 68 have their upper sis pivotally connected to the adjacent f ends of the rods 67 and are pivotally connected. to adjacent crank portions 69 of a shaft 70 journaled transversely between the enter ends of the beams 61. The crank oozi-tions (i-9 extend at various angles with respect to the longitudinal axis of the shaft T0 so that when the arms are connected thereto and the shaft is rotated, the arms will move alternately with respect to each other. Forks 71 are carried by the lower ends of the arms (8 and are disposed just above the lower end of the movable con- -veyer so as to throw the material on the means for operatively connecting the loader arms to the movable conveyer so that they -will operate simultaneously with the conplatform is moved about this pivot 10 so as to be arranged transversely of the main latform l. The shaft 58 is now rotated the crank handle 60 so that the cog .eels 59 will operate upon the rack bars so as to slide the rack bars longitudinally of and toward the rear end of the secondary platform inasmuch as the short uprights 5e are carried by the raising and lowering means to the outer or lower end of the movable conveyer. This conveyer will be mover downwardly at an inclination. This action course is permitted by the arms 45 and which are slidably connected respectively out the shaft 410 and the bracing bar ll. The windlasses 56 are now operated to adjust the lower end of the movable conveyer with respect to the ground. The pawl and ratchet arrangements 57 serve to maintain the parts in adjusted position. The main source of p wer not shown is now in operation to rotate the shaft 20 and inasmuch as the beveled gear 28 meshes with the beveled gear 29, rotary motion will be transmitted from the transverse shaft 20 to the transverse shaft 30 and by reason of the sprocket chain connection including the sprocket wheel 31 and chain 39 and sprocket wheel the shaft 18 of the stationary conveyer will be rotated and by reason of the u on which is frictionally engaged l apron 22, the latter will be actumove upwardly. During this by means of the beveled gears a2, the inclinen shaft 40 will be rotated. lnasmuch as the beveled gear .4? is slidably and yet rigidly connected to the. ell and is in mesh with the beveled gear 50. the short vertical shaft a? will be And finally, by reason of the beveled gear 51 on the shaft l7 being in mesh vith the her led 52 on the shaft the latter shaft will be rotated and as the slatted ain'on of the movable conveyor is ctionally engaged about the roller 36, this apron will be also moved upwardly. ..ctuating simultaneously with the conveyers is the loading means d this operation is effected by the chain '73 which is respectively trained about the sprocket wheel 7- roller of the shaft 35 and the sprocket wheel 72 on the crank shaft 70. Rotation of the crank shaft of course raises and lowers the arms 68 and inasmuch as they re pivotally connected to pivotally mounted and vertically swingable supporting rods 67, the arms will have the'action of a tedder, and

material, it will throw the material u on the lower end of the movable conveye the slatted belt 37 of which will carry the material up ll and deposit 01 "he slatted b of the stat nary conveyer which wi i consequently l .J it and thus depos t it in a suitable wagon body,
